POWER PUMP-HEAD.

State of California, have invented new andV useful lm rovements in PowerPump-Heads, of which t e following is a specification;

Myinvention relates to improvements inpump-heads, and especially inthose designed for use vwith double-acting deep-well umps of the typeshown, for instance, in my Fatent No. 737,274, dated August 25, 1903.

The obj ect of my invention is to provide a power-pump head which willbe very simple in construction,` easily set u and easlly knocked downforpshipment, w `ch is adaptable for either single or double actingpumps, anddwhich will be powerful and absolutely r1 1 Y glt consists ofthe parts and the construction and combination of parts, as hereinaftermore fully described and claimed, having reference to the accompanyingdrawings, in which- Y Figure 1 is a side elevation, in partial section,showing my pump-head associated with Fig. 2 is an end elevation, 1npartial section, of the pump-head at right angles to view of Fig. 1.Fig. 3 is a detail in perspective of aside plate. Fig. 4 is a detailshowing crank-gears adapted for single-acting pumps.

In carrying out my'invention l construct the frame of the head in fourparts, prefer-- ably castv and. suitably bolted together.l As shown, theframe'comprises two end castings A somewhat in the form of an isoscelestriangle, with the apex of each casting pro.- vided with a long bearingorvbox 2 for the arbor of a crank-gear 3. The two triangular endcastings A are spaced and braced by two side castings or plates B,having inwardly-projecting lugs 4 provided with perforations registeringwith corresponding perforations in the legs of the end castings A.y

Tie-bolts 5 extend through the several perforations of both, end framesand across the side plates, as shown. .Both side and end castings areflanged at thebottom, as represented at 6,-and when the bolts 5 havebeen tightened up and the entire assembled structure boltedl down it isextremely rigid.' In fact, the long tie-bolts 5 are purposely lextended`from end casting to end casting be- Specicaton of Letters Patent.Application l'ed August 16, 1904. Serial No. 220,923.

' cause ofthe ladditional bracing they a'ord.

At the same time the removal'ofthese eight bolts enables the entireframe to 'be quickly y dismantled. The end castings A have a second setof integrally-cast boxes 7, paralleling boxes' 2 and affording bearingsfor the drive-shaft 8, which receives motion from any suitable source ofpower. From shaft 8 power is transmitted to gears 3 by means of theinions 9.

T 1e rotary motion of the crank-gears 3 is converted into a verticalrectilinear movement of the sucker-rods 10 of the double-acting pump 1'1by means of the connecting-rods 12, each having one end pivoted on awristpin 13 on aV gear 3 and the other end pivoted y to a sleeve-casting14, slidable on the vertical stationary guide-rod 15, fixed at its endsin a respective end casting A. The lower end ofeach sleeve-casting has avperforated radial projection 16 for the engagement of a res ectiverod10.

he pump, while it may be of any type, is i Y here shown ofthedouble-acting variety illustrated in the patent previously referred to,in which there are two Youter valved cylinders reciprocal on thestationary valved barrels,

tol

the latter uniting at the to in a common discharge-pipe 17. Each cyinder is suspended from a rod 10 onv the outside of the barrels anddischarge-pipe, and the operation of the vrods and cylinders is soarranged that their action of suction and discharge shall be alternate.Thus the sucker-rods and cylinders work on a balance, leaving the weightof the water only to be actuallyalifted, saving the excess powerconstantly needed in other pumps to raise the extra weight of the -rodand plunger and obviating the strain usual in most pumps on the power. l

The ends of the arbors of gears 3 are each provided with adjustablecollars 18, so that snug smooth-runningbearings maybe always maintained.By giving the arbors a long bearing, las shown, a plentiful support forthem and the gears is afforded. This pumphead, while shown and describedin connection with a double-acting pump ,l is applicable l Fig. 4, maybe substituted for the two wristpins 13. rlhis construction saves takingoff or loosening from its bearings shaft 8.

Having thus described my invention, what I claim, and desire to secureby Letters .Patent, is

.1. A power pump-head comprising a frame made up of two end castingseach approximately in the form of an isosceles triangle and having longbearings integral with each of said castings for the reception of acranked gear-arbor, crank-gears liournaled in said bearings,interconnecting side castings between said end castings, long tie-boltspassing through the end castings and extending across the intermediateside castings, suitably-guided connecting-rods pivoted to saidcrank-gears, and means for imparting motion to said gears.

2. A frame for power pump-heads compri'sing end castings substantiallytriangular in for1n,jjournalboxes in axial alinement disposed at theapices of said triangular castings and intermediate side castingsconnecting and bracing the end castings and having perforated lugsagainst which the end castings bear, said end castings havingperforations corresponding with the perforations in the said castingsand tie-bolts passing through said perloiations and across the sidecastings.

3. A power-pump-head frame comprising triangular end castings havingintegral axially-alined ournal-boxes at their apiees, side castingsdisposed between and bracing the end castings and long tie-bolts passingthrough the end castings and side castings and extending across thelatter.

4. A power-pump-hcad frame comprising triangular end castings havingintegral journal-boxes at their apiees, separate side castingsconnecting and bracing the end castings, means for removably unitingsaid side and end castings and said side and end castings having eachbase-flanges provided with means for the attachment of the frame to aixed support.

In testimony whereof l have hereunto sei my hand in presence of twosubscribing \\'itnesses.
